indeed, only when using a microsoft account, which by the way is now required in the latest isos.
you can still bypass it but it requires being offline for the install. that being said, there are still many laptops with older windows version preinstalled that do not have the requirement; however users that don't care about this will just click the MS account option because the button was kind of hidden.
their reason for this is that you need to save the bitlocker recovery key somewhere, and they don't trust the users to do it properly (not even mentionning the UI for this would be horrendous) so it saves it to OneDrive.
It's actually still there and no need to be offline. Tested this the other with a brand new win11 22h2 install drive.
The workaround is to click "connect to my work account", then "domain join". Not Azure AD, but regular AD. This then presents you with the classic offline account creation dialog. It doesn't even ask you what the domain is.
It's still possible to only use a local one, but it's in an unexpected place, so I expect most people to go the online route.
